This 0.73ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG450008669 or 450008669. Listed at 4 retailers as of October 26, 2026, with prices from $260 to $1,102, a $842 spread on the same certified stone. MOH London lists it at $1,102. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
